Explanation:

Open cricothyrotomy is done when you are unable to secure a patent airway with less invasive means.

Emergency cricothyroidotomy is simply a surgical procedure. It is usually done by making an incision through the skin and cricothyroid membrane. It create space or gives room for putting of an endotracheal tube into the trachea when the airway is beyond possible control method.

Emergency cricothyroidotomy is done as a result of obstructed airways, congenital deformities and trauma to the neck/ head.
